9.4 Channel Count under WDM

The Babyface Pro’s ADAT optical interface offers sample rates of up to 192 kHz using a stan-

dard ADAT recorder. For this to work single-channel data is spread to two or four ADAT chan-

nels using the Sample Multiplexing technique. This reduces the number of available ADAT

channels from 8 to 4 or 2 per ADAT port.

Whenever the Babyface Pro changes into Double Speed (88.2/96 kHz) or Quad Speed mode

(176.4/192 kHz) all devices no longer available vanish automatically.

9.5 Multi-client Operation

RME audio interfaces support multi-client operation. Several programs can be used at the same

time. The formats ASIO and WDM can even be used on the same playback channels simulta-

neously. As WDM uses a real-time sample rate conversion (ASIO does not), all active ASIO

software has to use the same sample rate.

However, a better overview is maintained by using the channels exclusively. This is no limitation

at all, because TotalMix allows for any output routing, and therefore a playback of multiple soft-

ware on the same hardware outputs.

Inputs can be used from an unlimited number of WDM and ASIO software at the same time, as

the driver simply sends the data to all applications simultaneously.

RME's sophisticated tool DIGICheck operates like an ASIO host, using a special technique to

access playback channels directly. Therefore DIGICheck is able to analyse and display play-

back data from any software, no matter which format it uses.
